The SigCom ST-XTR01 Sentry Extender Kit expands the mounting depth for SENTRY front covers, accommodating pull stations that protrude up to 3¾ inches from the wall and providing conduit access from the top and bottom. The kit includes the extender, two conduit block plates, a compression plate, and four #10 Type A 4" Phillips round-head screws with anchors, and it is designed for use with the ST-FRC01 SENTRY front cover kit. Suited for indoor installations with deeper pull stations or surface-mounted back boxes, the Extender Kit enables deeper mounting while preserving alignment and serviceability (UPC 663426105027).
